Hence, breeding programs aimed at developing crop varieties with high chromium resistance or tolerance are much needed to reduce the toxic effects of chromium in plants as well as in humans. Fortunately, a new concept has been proposed that includes the screening and developing of plant varieties with low chromium content in the edible parts.
Other important uses include alloy steel, heating elements, pigments, leather processing, catalysts, and refractories. Of the chromite ore imported into the USA, the metallurgical industry consumed about 59 pct, the chemical industry consumed 21 pct, and the refractory industry consumed 20 pct.

1. Introduction. The background concentration of chromium (Cr) in soil range 1–300 mg kg −1 (Gill et al., 2016), while Cr(VI) levels it polluted areas may reach as high as 10,000 mg kg −1 (Li et al., 2022).Hexavalent chromate and trivalent chromite Cr(III) are common in natural environments, and the increase in Cr content mainly originates from natural …
Chromium is a trace element found in certain foods and the environment. There are two known forms: trivalent (chromium 3+) and hexavalent (chromium 6+). The trivalent form is found in foods and supplements, while toxic hexavalent chromium is found in …

Compared to three years ago, the production of chromium concentrate has tripled. Chromium ore processing was realized in 9 plants, out of 14 that were built in total. During 2018, the average growth in ore production was 43%, concentrates 35.4% and coloured chromium 16.5%. The mining sector is expected to grow again this year
2. Kazakhstan. Mine production: 3,800 MT. Last year, Kazakhstan produced 3,800 MT of chromium, up only slightly from its 2014 output of 3,700 MT. One major chromium operation in …
In a study with L. hexandra, the absorption of Cr 3+ was shown to be dependent on metabolic energy, with no relation to Ca 2+ and K + uptake channels. However, higher amounts Cr 3+ in plants that received Fe 3+ were observed (Liu et al., 2011).This suggests that Cr 3+ absorption by plant roots may be mediated in part through Fe 3+ complex carriers (Liu et al., …
